Dry Electrode Technology

Wearable Sensing's dry electrodes are based on D-Lab Pic 's leading Dry Sensor Interface (DSI) technology. The features of the DSI technology include:

No Skin Preparation:

Patented electronics allow high-fidelity EEG signal acquisition with no skin abrasion or preparation

No Gels:

Ultra-high impedance amplifiers mean that DSI sensors require no gels or fluids, and consequently do not leave any messy residue. All contacts are completely dry, no sticky or wet pads anywhere! This allows for irritation-free, long-term recordings, without risk of drying out!

Through-Hair Operation and Comfort:

Round-ended pinned active electrodes contact the scalp through hair and provide comfortable contact.

Uncompromising Signal Quality:

Signal quality is comparable to that obtained from conventional wet electrodes, with >90% correlation.


Mechanical and engineering designs eliminate motion and electrical artifacts WITHOUT the need for advanced filtering!

Rapid Set-up:

Easy-to-use headsets are typically self-donned in under 5 minutes with minimal or no adjustments needed

Even More Rapid Removal:

Easy-to-use headsets are instantly taken off, and do not require subjects to wash their hair afterwards

Ambulatory and Wireless:

Fully integrated batteries, amplifiers, digitizers, and Bluetooth transmitter allow for ambulatory use

10/20 Locations:

Headsets are designed to automatically and reproducibly position sensors according to the International System 10/20 on a wide range of head sizes.


Padding and spring-loaded designs provide for long-term wearable comfort unrivaled in the field of EEG. Headsets do not require chin-straps!
